Anyone know what the wiring and air line diagrams for the '06 Rubicon are? I have the axles installed, the pumps mounted, but I need to get them wired and plumbed.

The rear axle pump has 2 outlet ports (1 larger than the other), but no second spot on the axle for it to plug into. The larger air line is in the same factory bundle as the smaller air line (which goes into the diff) and the wiring that shows the lockers are engaged.

If you have the factory air pump bracket installed with the mounting holes down. The upper barbed fitting goes to your axle. The lower ones are routed back towards your fuel fill hose neck as the air intake. IRRC it should have a cap on the end similar to your axle vent hoses. I have the factory FSM but, can't copy and paste for you here.

EDIT......just run one line back to the filler hose. You can "T" into it at the pumps.

Per Axle:
You have 4 wires to contend with 2@ axle & 2 @ pump. These 4 wires do not inter connect.
The 2 @ the diff can be disregaurded, although I would want the indicator light (see below).
And 2 hoses, one of the 2 is an intake port and hooks to nothing. It is there to rout the air inake above flood level as the factory pump location is down by the "T" case. Power up the pump, one is pressure, one vaccum. Pressuse port goes to the diff, vaccum is the intake port.

Plug on diff is the signal (switch) that the locker has engaged. Has nothing to do as a function only reports back that the locker in fact engaged. Pumps stop by themselves based on pressure not this curcuit. The two wires (on diff) can be hooked to an indicator light. I have one light per axle. If you hook them up polarity does not matter.

The pumps IIRC have a pink, black and red wire. Red +12, Black -12, pink does nothing, I traced it back into the harness I got and it was hooked to the red wire. I think the pink wire is in pump motor plug, just don't recall. Don't buy into the pink wire function, for a add in (non factory rubi jeep) install it has no funtion for sure.

Lines are simple, I put my pumps below the hood on the drivers side shelf by brake booster. If you mount the pumps low you may want to add an intake hoses (1 per pump) and get them above flood level, like near top of the hood.
Run hose from pump to the diff connection, one pump for each axle. I used IIRC 3/16 fuel rated rubber hose. (may have been 1/8 ??)

So the larger tube goes to the fuel filler line for an air intake for the pumps?

If that is the case, how come only 1 pump has the 2 air line fittings on it?

Look at the thread for swich set ups, mine is in there if you like.

Thanks for the info.

So the wiring coming from the diff is a normally open switch that closes when the locker is engaged?

I am planning on putting indicator lights somewhere in the dash so I know they are locked.

Are the pumps pretty water tight? Last time I was wheelin, I had some water in the floor. I like the idea of them under the seat, just don't want to soak them and fry them.

yep... a normally open switch.

not sure on the pump ports
I can look at mine, they came as a set mounted on the factory bracket form the orig. owner.
I looked they look the same to me, maybe you have a busted port. IIRC mudb8 or someone has a thread on reparing pumps & ports

Yes they bleed down. The indicator light will stay on after you turn the locker pump switch off for a tick or so. (providing you indicator is not powerd up by the pump feed)

Don't be alarmed

And when turning on you may need to drive up too maybe 8' sometimes to get the lockers to engage (I'm pretty sure there are pins in the diff that need to align with holes then slide into place)

another tid bit .. the outside air line connection tube changes to a rubber hose inside the diff. The front diff internal rubber hose has twice slid off on me. Once when I got the axles and second about 9 months later. That time I put a plastic zip tie around it. The first time I though maybe the pump was shot cause it would not stop running unless I turned it off and of coarse no engagement.

BTW my pumps are on one 10amp fuse

Thanks.

I was going to power the indicator lights from a separate 2A power source so they wouldn't immediately go off with the pump power.

Does the plug coming out of the diff for the indicator lights ground when it closes?
